Description:1.SW-520D is a ball type tilting vibration sensing unidirectional trigger switch. The appearance is sealed with heat-shrinkable tube to protect against dust and moisture.2.This switch is suitable for touching off the small current circuit not suitable for acting as the mains switching. Applied to the electronic toys, small household appliance, sports equipment and anti-theft devices.3.Made of metal, the electrical characteristics are similar to the mer-cury switch, but it is not as dan-gerous as the mer-cury switch and has environmental problems. It has a single-passing characteristic when shaking, and it is more convenient and safe to assemble.
